I have a ULA Circuit and for the past few hikes I have had a single zPacks shoulder strap pouch which has been great for storing things that I want to keep available while hiking. My Circuit has hip belt pouches as well which I use to keep food to eat while on the move as well as my camera. For my upcoming PCT hike, I was planning to buy an additional zPacks shoulder strap pouch since it has been so useful for me and I could use a bit more additional storage up front and it would free up space in my pack's side pockets for heavy water carries. However, I got to thinking about the zPacks Multi pack as a possible alternate solution. It is obviously much larger and could possibly eliminate the need for shoulder pouches altogether. Then I could use the shoulder strap loops for even more water on the desert sections of the PCT, if needed.
Has anyone used the zPacks multi pack with a ULA Circuit as I'm describing here?
